FLDING CASE A Benjamin B. Freifeld, New York, N. Y. Application May 12,1942, Serial No. 442,652

(Cl. 12S-l) 6 Claims.

This invention relates to improvements in folding cases for the carryingand preservation of personal papers, such as ,the newly issuedGovernment paper ration certificates.

The primary object of the invention is to provide a folding case intowhich personal papers such as food rationing paper certificatescontaintear-away stamps or coupons may be kept to prevent soiling andwrinkling during handling over the period of time for which they areissued.

Another feature of the invention resides in a folding case in which theidentifying indicia of the certificates and the tear-away stamps areexposed when the case is open to enable the tearing away of the stampswithout removing the certificates from the case.

Another feature of the invention is to provide what may be termed aloose leaf binder in the form of a wallet or folding case in which loosepaper sheets may be securely bound therein without the aid of extraneousfastening elements.

A further feature of the invention is the provision of a folding case inwhich the papers are easily insertable and removable, and which issimple and inexpensive of construction.

Other features of the invention will become apparent as the followingspecification is read in conjunction with the accompanying drawingy inwhich:

Figure l is an inside plan view of the folding case in open position andwith the securing flaps extended, a portion of the case being brokenaway in section.

Figure 2 is a view similar to Figure 1, but showing three papercertificates in fastened position therein, the lower right corners ofthe certicates being broken away.

Figure 3 is an enlarged transverse sectional View on the line 3 3 ofFigure 2.

Figure 4 is a perspective View of the case in closed position.

Figure 5 is a plan view of a modified form of case formed from a singleblank of material, a port-ion being broken away in section.

Referring to the drawing by reference characters and at present to thepreferred embodiment of the invention illustrated in Figures 1 to 4 ofthe drawing, the numeral I0 designates a folding case or loose-leafbinder in its entirety. The

case I0 includes a pair of stii rectangular shaped cover members I I-I Ihingedly connected in book fashion as at I 2 by flexible bindingmaterial I3. The cover members II-II may be made of one or more plies ofcardboard I4 suitably covered by 55 one certificate C is to be carriedin same are placed flat in unfolded position, one

imitation leather cr like outer binding material i3. Secured to theinside of each cover member II is a binding or holding unit I5, the samebeing made in rights and lefts for attachment to the respective hingedlyconnected cover members, Each binding or holding unit i5 is ccn-`structed from a single blank of material such as leather, cardboard, orcardboard having a fabric backing. Whereas the material from which eachunit i5 is constructed is relatively stiff, it is capable of being exedand folded in a manner and for reasons hereinafter explained. Eachholding unit comprises a rectangular attaching panel I6 of a sizeslightly less than that of the cover, and which panel is centeredrelative to the cover so as to lie within the confines of the same. Anadhesive I'I secures the panel It to the inner side of the cover asshown in Figure 3. Formed integral with the top edge of the panel I6 isa substantially L-shaped inwardly extending flange I 8, the long portionI9 thereof extending entirely across the panel I5 while the shortervertical portion 22! terminates some dis-V tance short of the bottomedge thereof. Formed integral with the vertical short portion 2G andfolded inwardly therebeneath is a glue flap 2I which is adhesivelysecured to the portion Vof the panel It which it overlaps. The L-shapedflanges Ill cooperate with the panel I6 to provide right angle cornerpockets P. When the coverl members I I -I I are open as illustrated inFigures l and 2, the angle corner pockets P are in reverse relation andslidably receive and hold the top folded edges of the sheets orcertificates to be held by the case. Formed integral with the lower edgeof the panel I6 is a free tongue flap 22, the side edges of whichconverge as at 23. The nap 22 is of a length slightly less than theWidth of the panel I6 so as to lie beneath the Lshaped ilange I8 whenthe tongue nap is folded inwardly on the score or crease 2li.

In the drawing I have illustrated a folding case IIE for holding andpreserving one or more Government ration certificates C, three of whichhave been illustrated. Each certificate is rectangular in plan havingits lower edge provided with a double longitudinal row of stamps orcoupons S to be torn therefrom in exchange for the purchase of rationedcommodities. If more than the case, the

upon the other in alined relation. The certificates are foldedlengthwise on their mid-portion M and inserted with the folded edgefirst, in-

wardly of the open cover member until the top folded edge M and upperportions of the free outer side edges enter the pockets P and liebeneath the L-shaped flaps I8. The operator now folds the to'ngue flaps22-22 upon the creases 24-24 and by a slight flexing of the tongueflaps, the same are inserted inwardly between the folds of the innermostfolded sheet or certificate C as best seen by reference to Figure 3. Theinner ends of the tongue flaps 22 and a portion of the outer edgesthereof lap the plane of the portions i9 and 2Q respectively of thepocket forming flaps I8, thus preventing the accidental slipping out ofthe tongue flaps which with the flanges I8 prevent accidental removal ofthe folded certificate. Thefree edges of the certificate C containingthe tear-away stamps S are face up when the case li) is open, whereuponthe same are readily accessible for removal without disturbing theremainder of the certificates. The certificates also containidentification indicia above the rows of stamps which is exposed to viewwhen the case l is open. iii/*hen the case Iii is closed as shown inFigure 4, the certificates further fold on the transverse creases T andthe fianges iii-i9 and cover members II-Il are in confronting relation.Thus it will be seen that the certificates C or other loose sheets maybe held in a bound condition between the two cover members ll-H and keptin a neat and clean condition. Io remove the certificates C or sheets,it is only necessary to withdrawn the tongue flaps 2"-22 from betweenthe folds of the innermost certificate or sheet, and then slide thecertiiicates or sheets from beneath the flanges I8-!S.

In Figure of the drawing, I have illustrated a modified form of theinvention in which the folding case or binder is constructed from asingle blank of leather, imitation leather, cardboard or other likematerial. The blank of material is cut, creased, and folded to providehingedly connected complementary cover sections i l-l i having integralinwardly folded substantially L-shaped naps ISL-IS', the short sideportions 2% thereof having rintegral inwardly folded attaching flaps 2l'which may be glued or stitched to the cover sections libl. Connected tothe cover sections H-i I along the creases 24-2l are tongue flaps'ET-22. In use, the folded sheets are inserted beneath the flaps {SL-I'in the same manner as hereinbefore explained and the tongue flaps 22'-22folded inwardly beneath the folds of the innermost sheet.

While I have shown and described what I con- Sider to be the mostpractical embodiments of my invention, I wish it to be understood thatsuch changes in materials, design, and construction as come within thescope of the appended claims may be resorted to if desired.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is:
